MX43 gas detection controller (up to 32 transmitters)
The Oldham MX43 multi-channel gas controller has been developed to meet the user's needs in terms of flexibility, quality and ease of use. It is a digital and analog controller for monitoring gases present in the atmosphere with the possibility of connecting up to 32 gas detectors in 8-line version.
This very versatile controller has many advantages such as exceptional modularity, a backlit 4”graphic LCD screen, 5 programmable alarm levels per channel, as well as a USB port (optional) for measurements and events archiving. Detailed description
The MX43 gas detection unit
3 MX43 versions availableThe MX43 gas controler is available in 3 versions to meet the greatest number of applications:
- MX43M-4: 4-line wall version allowing the connection of 4 analog 4-20 mA sensors or up to 16 digital sensors distributed over 4 lines
- MX43M-8: Wall-mounted version 8 lines allowing to connect 8 analog sensors 4-20 mA or up to 32 digital sensors distributed on 8 lines
- MX43R-8: Rack version 19’’ / 4U 8 lines allowing to connect 8 analog sensors 4-20 mA or up to 32 digital sensors distributed on 8 lines
Many input/output modules
The MX43 gas detection unit accepts various input/output modules to increase the system's capacities and flexibility.
- Addressable module with 8 analog inputs that can receive all types of 4-20 mA analog transmitters
- Addressable 4 or 8 relay module (+ 2 logic inputs) that can be deported as close as possible to the controls.
- Addressable module with 16 digital inputs that can receive all digital information (emergency stop, limit switch, fire alarm).
- Addressable module with 4 analog outputs for connection to a recorder, a PLC, a building management system, etc.
